What is 152,909 rounded to the nearest hundred thousands

lara31 [8.8K]

152,909 rounded to the nearest hundred thousands is 200,000.

Rules of rounding numbers
1) if the number being rounded off is followed by 0, 1, 2, 3, and 4, round the number down.
2) if the number being rounded off is followed by 5, 6, 7, 8, and 9, round the number down.

1 is the number on the hundred thousands place. It is followed by 5. We round 1 up to 2. Thus 2 is now in the hundred thousands place.

Use one unit multiplier to convert 5,000 meters to centimeters

wel

Answer:

5000 meters = 5000 × 100 = 500000 centimeters.

Conversion of 5000 meters to other length, height & distance units

5000 meters = 5 kilometers

5000 meters = 50000 decimeters

5000 meters = 5000000 millimeters

5000 meters = 5 × 1013 angstroms

5000 meters = 3.11 miles

5000 meters = 2730 fathoms

5000 meters = 5470 yards

5000 meters = 16400 feet

5000 meters = 49200 hands

5000 meters = 197000 inches

5000 meters = 43700 fingers

5000 meters = 1562 1

Triangle sum theorem WILL MARK BRAINLIEST

sergiy2304 [10]

Answer:

So for a hint to help you...when you are looking at a triangle on a 180 degree line, each angle adds up to 180 degrees. So for example, on #9 on the top of the triangle, one of the angles is 49 degrees so you want to subtract that from 180 ( 180 - 49 = X ) ( X = angle 1 and 2 ) so angle 1 and 2 added together equals X. In this case, ( X = 131 degrees ) Every triangle equals 180 degrees too. So since this angle has 3 different angles on the line, you can do the rest of the problems and come back to these because you can subtract angle 4 and 73 to get angle 2.

(still on #9) Angle 3, as you can see only has one other number beside it (73) so it makes this one very easy. ( 180 - 73 = X ) ( X = 107 ) Angle 3 = 107 degrees

Angle 5. Subtract the 49 above angle 5 from 180 and the result will be angle 5. ( 180 - 49 = X ) ( X = Angle 5 ) X/angle 5 = 131.

Now you can get angle 4, which gives you angle 2 and 1. ( 180 - 131 = Angle 4 ) (Angle 4 = 49)

Angle 2. In the triangle, we have 73 degrees, and 49 degrees. So the equation for this one is, ( 180 - 73 - 49 = Angle 2 ) ( Angle 2 = 58 )

Angle 1. On this line, we have 49 degrees and 2=58 degrees. ( 180 - 58 - 49 = Angle 1 ) ( Angle 1 = 73 )

Lastly, Angle 3. The side of this triangle will also equal 180, just like the top line. Angle 1 = 73 degrees so as you now know, subtract that from 180 and get angle 3. ( 180 - 73 = Angle 3 ) (Angle 3 = 107 )

1: 73 degrees

2: 58 degrees

3: 107 degrees

4: 49 degrees

5: 131 degrees

I know this is a lot to read, but I really hope I explained it to where you can understand it now.

While hovering near the top of Ribbon Falls in Yosemite National Park at 1600 feet, a

ella [17]

Answer:

a)The sunglasses hit the ground at t=0 seconds

b)The maximum height h(t) = 1600feet

Step-by-step explanation:

Step(i):-

Given that the polynomial function

h(t) = -16 t² + 1600 ...(i)

Differentiating equation (i) with respective to 't' , we get

$\frac{dh}{dt} = -16(2t)+0$

Equating zero

$\frac{dh}{dt} = 0$

⇒ -32t =0

⇒ t =0

The sunglasses hit the ground at t=0 seconds

Step(ii):-

Again differentiating with respective to 't', we get

$\frac{d^{2} h}{dt^{2} } = -32(1) = -32$

The maximum height at t=0

h(t) = -16 t² + 1600

h(t) = 1600feet
